Tensile Strength Formula:
| From: | To: |
Tensile strength is the maximum stress that a material can withstand while being stretched or pulled before breaking. It is a fundamental mechanical property that indicates how much force per unit area a material can endure without failure.
The calculator uses the tensile strength formula:
Where:
Explanation: The formula calculates the maximum stress a material can withstand by dividing the maximum force by the original cross-sectional area of the specimen.
Details: Tensile strength is crucial for material selection in engineering applications, quality control in manufacturing, and structural design to ensure materials can withstand expected loads without failure.
Tips: Enter maximum force in Newtons (N) and cross-sectional area in square meters (m²). Both values must be positive numbers. The calculator will compute the tensile strength in Pascals (N/m²).
Q1: What units should I use for the inputs?
A: Force should be in Newtons (N) and area in square meters (m²). The result will be in Pascals (N/m²).
Q2: How does tensile strength differ from yield strength?
A: Yield strength is the stress at which a material begins to deform plastically, while tensile strength is the maximum stress it can withstand before fracture.
Q3: What are typical tensile strength values for common materials?
A: Steel: 400-2500 MPa, Aluminum: 90-600 MPa, Concrete: 2-5 MPa, Wood: 30-120 MPa (parallel to grain).
Q4: Why is cross-sectional area important in the calculation?
A: Tensile strength is a stress measurement (force per unit area), so the cross-sectional area normalizes the force to account for different specimen sizes.
Q5: Can this calculator be used for all materials?
A: Yes, the formula applies to all materials, but proper specimen preparation and testing conditions are essential for accurate results.
